Renewable Energy Policy Landscape

Auctions are the most rapidly expanding form of renewable energy policy support.


Opportunities and Challenges in the Power Sector

• Integration of VRE • Forecasting resource variability • Efficiency measures • Storage Technologies • Smart grids and load management • Energy pricing strategies • Effective balancing strategies • International technology and integration standards


Storage will be Key

Some Closing Comments

• Even with short-term oil price drops, renewables are now cost-competitive choice for power sector in many cases

• PV Applications, both distributed as well as central station, offer significant benefits - Increase grid and energy security - Improve our environment - Enhance local economy

• Issues for ICAO to address: - Creation of an enabling policy environment - Workforce development - Access to capital investment
